BOILER.

Application filed June 1921. Serial No. 477,638.

My invention consists of a furnace havthey are removable, tion chamberformed an additional combusof opposed water legs,

and fuel flues on said structure, said fiues forming separate heat ngelements for said legs, and communicatlng vertlcal passages connectingsaid flues forming pluralities off an upper chamber the products ofcombusfuel receiving lines and 1 adapted to receive tion from saidfiues, said fiues serving to subject the water legs to increased heatingactions It consists also. of a batiie plate in said heat receivingchamber adapted to cause the ascending products of combustion to bedeflected downwardly in said chamber to the place of exit jacket on saidtherefrom, thus heating a water upper chamber.

. It consists also of a perforated plate which may be lowered in theheat receiving chamber to act to dampen the fire and when not requiredmay be raised the aforesaid baffle plate.

It consists also in forming bricks placed side by above the otherwithbetween theirjoints structure of separate side and in tiers one outmortar or cement and supported on the fire brick so that air maypassthrough said joints into the fire pot and with. v

The invention is so supply the latter theresatisfactorily illustrated inthe accompanying drawing, but the import-ant instrumentalitiesthereofpmay be varied, so it invention s not tails shown and limited isto be understood that the to the specific dedescribed, as long as theyare within the spirit or scope of the claim.

Fig. 1, represents a partial vertical section and partial embodying myinvention Fig. 2, represents a front elevation of a furnace horizontalsection thereof on=line 22 of Fig. 1.

Fig. 3, represents a horizontal section of a portion on line 3-3 of Fig.1.

Fig. 4, represents "a vertical section showing the fuel inlet and thedoor therefor.

Similar numerals of corresponding parts.

Referring to 1 designates same being composed. of ture formed of firethe drawings 1 the fire pot of reference indicate a furnace, the a firebrick strucbricks 2 placed side by side and imposed in series of tiersone on top of the other and app earing on the exterior of the fire potthey being clamped between the upper and lower plates 3 which aretlghtened by the bolts. 4, the structure being supported on the ash pit5. 6 is the a1r supply door and 7 its supporting framei Supported on theupper clamping plate 3 of the fire pot structure are the intur'ned waterholding sections '8 wh-ose'inner terminal walls are separated formingthe vertical fiues or passages 9. The legs are formed of opposite halfsections each of which is connected with the side walls 10 provided withflanges 11 through which are passed the bolts 11 whereby said walls andconsequently said water. legs may be connected and clamped firmlytogether.

The walls 10 are set out from the adjacent side walls of the water legsS'providingv water receiving passages 12 which are in communication withthe interiorofsaid legs and so have thewater circulate through said legsand passages. 1

The inner side walls'of said legs 8 converge'from the outer wallsthereof to the centres of said legs where they join the walls of thepassages 9 between adjacent legs forming a series of fuel receivingflues 13, adjacent fiues being in communication by said passages 9as'most plainly shown in Fig. 2. Said fines are open at the top wherebyfuel may be directed into the same. They are also open at the bottom andso placed in communication with the the converging nature of' the sidewalls of the flu-es 13 they produce large heating sur faces for thewater surrounding the fines.

The legs are provided with suitable intakes 14 for supplying the legswith water. The fiues 13 and passages 9 form also comfirepot. Owing tofuel at the open tops of said flues, fuel also descending and enteringthe fire pot below by which means the water legs are further subjectedto the heat from said fiues thus highly heating said legs andconsequently producing large volumes of hot water.

Superimposed on the fines 13 is the chamber 15 which is adapted toreceive the products of combustion from said flues, the bottom of saidchamber having therein the opening at by the swinging perforated damper17 which being hinged to the adjacent portion of the lower end of thechamber 15 may be lowered over said opening and so serve by itsperforations as a damper for the fire when so re- 16 which may becovered in part in elevated position.

properly drawn from the damper the latter quired. The damper 17 may beraised clear of said opening and then held in elevated position by-thecatch 18 on the upper limb of the imperforatedbafi'ile plate 19 whoselower end is secured to the adjacent portion of the chamber 15, saidplate then rising from said portion to nearly the top of the chamberleaving a passage or space for the products of combustion as shown bythe large arrow, Figure '1. The upper limb of the baffle plate issecured to the top of the chamber 15 by the bolt 20." The catch 18 ishinged to the top limb of the baffle plate 19 and its nose portion isadapted to engage the adjacent edge'of the damper 17 and so hold thelatter When the catch is is released and so may be loweredover theopening 16 for the purpose h-ereinbefore referred to.

It will be noticed that the chamber 15 is formed of an independentsection or a section separate from the sections'of the water legs 8 andfuel lines 13. In the side wall of the chamber is the fuel inlet 21which is provided with the door 22 which is provided with the damper 23,the latter when not required to be opened being adapted to be closed bythe cap 24: which is removably fitted on the wall of said damper.

In the side of the chamber is an opening occupied by the collar 25 forthe "exit of the products of combustion and the attachment thereto ofthe smoke pipe or flue 26. The wall of the chamber 15' is surrounded bythe Water jacket 27 The exit of the hot water may be as at 14*.

The fuel is supplied through the inlet 21 and so enters the fiues 13,the passages 9 and the fire pot in the brick structure, the fuel burningfrom the latter through said passages 9 and flues 13 and the products ofcombustion then being'directed to the passage or space at the top of thebaflle plate 19 the latter being inclined inwardly from one side of thebottom of the chamber 15 to the opposite side thus uncovering theeXitcollar 25 of the exit flue 26 which directs the products ofcombustion to the atmosphere.

Should it be desirable; to dampen the fire the door 22 is openedrendering the catch 18 accessible. The catch is then operated to releasethe damper 17 when the latter then drops or lowers on the base of thechamber 15 over the opening 16 therein, when the productsof'combustionfrom the tines 13 pass through the perforations or openingsin the damper. The bricks S'are placed side by sideand on each otherwithout mortar or cement and so admit air to pass betweenthe jointsthereof and so enter the fire pot formed by the brick structure. I p Ild hen the bolts 4 are displaced the fire bricks may be removed from theexterior'of the furnace by being withdrawn outwardly therefrom.

I claim: In a boiler, an ash-pit, a horizontally arranged framesuperimposedthereon and se said second section, and a perforated dampersecured: to said battle and adapted tobe lowered into a. horizontalposition above said first ment-ioned section and in afplanesubstantiallybelow the opening as closed by'said firing door.
